The structure of the labeling machine (rotary) can be divided into the mechanical principle and the best debugging method of the machine, because each device of the labeling machine can be adjusted according to their needs, so as to improve the quality of the labeling. Bad, it is mainly due to the cooperation between the target plate part and the standard box and the cooperation with the clamping drum, especially the tangent between the target plate and the glue box. These are all done by the cam, and the cam is pressed Design needs to vary the rotation of the target. We all know why one side of the moon is always facing the earth, because every revolution of the moon is a month, just as its rotation is a month. Therefore, we cannot see the other side of the moon. We accomplish tangent to each device by varying the target's rotation as it revolves somewhere. The most suitable tangent between the target plate and the rubber roller is 0.1mm. If the target plate is a rubber plate, its strength is 50 Shore, and if the target plate is an aluminum alloy, the strength of the rubber roller should be 65-70 Shore.
The tangent between the head target plate and the body target plate and the rubber roller is 0.1mm. If the pressure of the upper and lower target plates is uneven, the three positioning screws of the rubber roller can be adjusted to adjust the angle of the rubber roller to vertical. When adjusting the tangent position between the target plate and the rubber roller, first turn the 5mm left of the target plate to the tangent position of the rubber roller, then slowly pull up the rubber roller and put it down, and then continue to rotate the target plate to the right 5mm tangent position , and then slowly pull up the rubber roller to test whether the weights are the same. It is between 15 and 2mm, so that the push device in the standard box moves continuously with the tangent of the target plate. If the forward and backward movement is blocked, the tension of the standard box tension spring can be adjusted.
When the target plate is tangent to the labeling drum, it is best to adjust the finger clip in the labeling drum to the 5mm position of the paper clip, and then adjust the distance between the drum pad and the target plate tangent to 5mm. 1-1.5mm, to prevent the glue from passing to the label drum, if the distance is too large, the label paper will be tilted.
The groove depth and groove width on the target board are preferably 0.5mm, and the best line is 0.8mm, because the purpose of the groove on the target board is to make the standard fast dry and reduce wrinkles. What needs to be explained here is a standard On the paper, there is a glue with a width of 0.8mm every 05mm, so that the water in the 08mm glue is immediately absorbed by the left and right, so it can be cured in a few seconds, making the brand glossy.
It is best to process the header plate into an angle-adjustable type, because the upper and lower marks in many trademarks need to be centered, and it is much more convenient to have the angle adjustment. The tangent of the cambered surface R=55mm between the label drum and the bottle can be divided into the head label tangent method and the neck label tangent method, because the tangent position of the neck label will sound the inclination and verticality of the neck label, because the bottleneck It is ladder type. When the top label sponge is tangent to the wine bottle, the shape of the sponge should be sanded to match the shape of the wine bottle to form a trapezoid; in the production process, when the sponge is tangent to the wine bottle, the top label is often inclined. It is not a mechanical problem or an adjustment problem. It must be that the sponge and the wine bottle are tangentially pushed the top mark, because when the cam in the top mark drum pushes the sponge out, its diameter becomes larger in an instant, so its speed also increases. Immediately speed up, at this time, the speed of the large turntable of the brush mark remains unchanged, causing the speed difference to push the top mark obliquely. Therefore, it is necessary to sand the sponge very carefully to reduce friction. The bottle tray in the large turntable is fixed as designed If the bottle rotates on its own, after the bottle is tangent to the label drum, turn the label 9 degrees to the right, turn left 9 degrees to the inside of the head label, then turn right 180 degrees to brush the outside of the head label, and finally stick the back label. This is theoretically true. This should be the case, but it is not enough to rotate 180 degrees in actual use, it will make the bottle easily touch the label drum pad and cannot be adjusted. It is best to be as light as 183 degrees. In a parallel state, when brushing the neck label, it should be parallel to the taper of the bottle neck, so that the brush is evenly stressed on both sides of the wine bottle, so as to prevent the label from tilting and shifting. The fiber pattern of the label paper is processed. For example, if a label is placed in water, if the upper and lower sides are rolled up, it is correct. If the left and right sides are rolled up, it is caused by the error of the printer during the printing and cutting process. In the process of using the label paper, it should be noted that after opening the box and taking out the label, the box must be closed immediately, and the label should not be placed outside to avoid contact with the air, because the label will be deformed when it encounters wet and dry air, thus Seriously affect the labeling quality.
